So, I tried to clarify a bit that we have display aspect ratio selectable, updated cingg team copyright year, added even more finegrained sar/dar reporting (guessed, container detected, codec detected).

I tried to use libavutil function for reporting SAR in setformat.C but it need some dynamic gui subwindow/object, not static BCTitle... so just prototype that does not update as you update window, only calculated on window objects create time, so each time you reopen set format window.

3 new git diff patches hopefully for application

0003 should be applied on top of 

0001-Add-guessed-detected-SAR-DAR-values-to-ffmpeg-asset-.patch

from another thread

one plain diff patch just for showing where SAR info might surface if I ever learn now to create dynamic text subwindows :)

oh, I calculated SAR wrongly in setformat patch, so this one should  obviously only considered as placeholder/mockup.

Still not sure to what exactly w/h ratio fields in setformat window relate - I thought about preset vs canvas size but this does not hold up in testing ...

According to the Cin-CV manual:
http://cinelerra-cv.wikidot.com/cincv-manual-en:project-attributes#toc4

W Ratio, H Ratio
Sets the ratio of the new canvas size (W, H) to the old (previous) canvas size (W, H). The new canvas size is recalculated based upon a certain factor in the W Ratio, H Ratio fields. A practical use-case: The current resolution is 640x480, and for some reason you want it to be 1.33 times wider. You don't have to calculate what 640x1.33 is; you type 1.33 into the "W" input instead, and Cinelerra calculates it for you. This tutorial explores in more detail these settings. It is in Russian but easily translatable with GoogleTranslator, DeepL or similar.

The latter Tutorial can be translated ......

Excuse me for the parlance used in the refered blogpost.. I was not aware it had been mentioned before on our mailinglist...
